To all whom, it may concern:

Be it known that I, WmsLow I. WENT- WORTH, a citizen of the United States, resid ing at Brocktomin the county of Plymouth and State of Massachusetts, have invented new and useful Improvements inMa-chines for Manufacturing Boot and Shoe Heels, ofwhich the following is a specification.

My invention relates to machines for manufacturing or building up boot and shoe heels, and has for its object to provide a machine for automatically forming and shaping such heels, to provide .means for so automatically forming the heels as to impart thereto a dished conformation or seat to conform to the heel structure of the boot or shoe without the necessity of the utilization of rands, and,

third, to provide in an automatic heel-building machine means by which the height of the heel may be varied.

My invention has also for its object to improve the construction and mode of operation of machines for building boot and shoe heels.

To the ends stated the invention consists in a heel-building machine having the novel combination and arrangement and mode of operation of parts as hereinafter described and claimed.

In the accompanying drawings, illustratmg the best-known and preferred embodiment of my invention, Figure 1 is a view, party in elevation and partly in section. Fig. 2 is a front elevation. Fig. 3 is a detail view showing the movable preliminary heelform, which is adapted to receive the several lifts composing the he l, and its cooperative relation to the mold-chamber through which the material is passed and from which it is expressed, as hereinafter described. Fig. 4 is a sectional view illustrating the heel-mold, the heel-seat die, and adjacent mechanism. Fig. 5 is a plan view illustrating the seatforming die, the roller for shaping the vertical surface of the heels, and corelated ele-' ments. Fig. 6 is a plan view illustrating the means for adjusting said roller to cooperate with different-sized heels. Fig.7 isa detail of the track on which said surface-shapingroller carriage travels, showing also the ratchet with which said carriage is inter-nut tently engaged and by which it is caused to travel on said track. Fig. 8 is a detail view of the end of the arm which cooperates with the lock and connects and disconnects the heelsurface-roller carriage with the means for driving the same. Fig. 9 is a perspective view of the heel-seat die.

In the said drawings the reference-numeral 1 designates a framework orv support of any suitable character, connected to which is a table 2. Arranged to slide on this table is a preliminary heel-form 3,-in which heel-lifts sufficient to construct a heel of the desired height are arranged by a workman and in which they are-carried tothe mold 4, hereinafter described, said lifts being supplied with a suitable cement whereby they are secured together.

The numeral 4 designates a mold chamber or passage through the table 2 and conform.

mg in outline to that of the heel-lifts of which the heel is to be constructed. As shown, this mold-chamber is formed in a suitable metallic casting 5, set into the table 2 in any desired manner. It is designed that the workman shall iplace in the preliminary form 3 a number 0. heel-lifts sufficient to form, in finality, a complete heel and shall then slide the preliminary form into coincidence with the mold 4.

The numeral 6 designates a plunger fitted to move in a guide-standard 7 and provided with anadjustable die 8. The plunger is operated conveniently by a rock-arm 9, actuated through the medium of an eccentric ring 10, connected thereto, which ring is engaged by an eccentric '11, carried by a countershaft 12 of the machine, which counter-shaft is driven by a gear 13, meshing with a gear 14, mountedon an intermediate shaft 15, driven by a gear '16, that meshes with a gear 17 on the .main driving-shaft l8. Beneath the mold 4 is arranged a support 19. which offers resistance to the plunger 6 and die 8, and therefore takes an active part in the formation of the heel-stock, and by which, together with the mold 4., the stock is held while being shaped, as hereinafter set forth. This support 19 serves. furthermore, as a heel-seat die. the formation of which (shown enlarged in Fig. 9) operates to dish the ap-. propriate surface of the heel to form a heelseat conforming to the shape of the heel portion of the boot or shoe it is to receive. By imparting this dished form or heel-seat formation to the heel the necessity of utilizing the commonly-known rand is dispensed with. It is designed according to my invention thatscveral batches of heel-lifts, each batch mined height of the heel to be manu actured,

It. will therefore be seen that in the pro ess of the incomplete heel through the mo d it receives a plurality of compressions between the die on the plunger and the heel-seat die, whereby the several lifts thereof are well compacted together, and that portion of the.

heel which is lowermost in its pro ess through the mold receives the dished or eelseat formation imparted by the heel-seat die, as hereinbefore mentioned.'

In order to permit of variation in the height of heels built up or manufactured by themachine, the heel-seat-d'ie is adjustable with relation to the mold, a suitable means for accomplishing this being as follows: The heelseat die is provided with a s indle 20, that passes down through the ereinafter-de scribed roller-carriage and enters a sleeve 21, suitably formed or attached to the frame 1. This spindle is provided with a key 22, that engages an appropriate slot in the sleeve to prevent rotation of the spindle. Rotation thereof may, however, be prevented in any other suitable manner. The lower end ofthe spindle is suitably threaded, as shown M23, and a nut 24 is mounted'in the sleeve and engages the screw-thread of the spindle, whereates against the vertical face or edge of the 4 heel and is suitably shaped to impartthe desired curvature or contourto sai edge of the heel.

Because of the fact that the contour of the heels is not circular, but ap roximately elliptical; in shape, it is desirable that the heelsurface roller 26 shall be ca able of a variable ath of movement to con orm to the pecuiarity of the contour of the heel, and to this end it is pivoted to the carriage, as at 27, as before mentioned, and is operatively engaged by a controlling device consisting of a roller 28, traveling upon a stationary track 29, which track is provided with elevations 30, coincident with the minor diameter of the heel-seat die and the heel to be manufactured, whereby in the rotation of the carriage 25 the said controlling-roller will ride upon saidelevations'and tilt the said heelsurface roller 26 inward toward the heel, and

when ridingu on the lower portion of the track said hee surface roller will be permitother end of which'is provided with apinion' caused 'to rotatewith said wheel.

cameo ted to move outward. The heel-surface roller is thus caused to movein a path conforming to the shape of the heel and adequately press and give shape to the vertical ed e or surface thereof. it isdesigned that the ro ation of the carm'old onto the heel-seat die a sufiicient. quantity of material to. constructs, heel, and to this end: the said carriage is'interinittently locked to a ratchet-wheel '31, formed rigid with a hub .32, having a pinion 33 in mesh with a pinion .34 on one end ofa shaft 35,the

36, meshing with a gear 37 on the intermediate shaft 15, whereby said ratchet s cons'tantly rotated. To connect the carriage 25 .riage; 25 shall bev caused iriiermittently and. after the plunger has expressed from the with said ratchet, so that it will be'thereby caused to rotate, said carriage is provided with a locking-d6g 38, one arm of which 1s adapted to engage the teeth of the ratchet and the other arm of which is adapted at eachrotation of said carriage to enter the forked end of a pivoted arm 39, the other end of 5' which is enga ed by a cam 40 on the countershaft 12,-whic cam is so timed in relation to the plunger-o crating mechanism thatafter a heel-stock as been expressed from the moldonto the heel-seat die the forked end'of 5 said .arm'will be free to respond tothe impulse of a s' ring 411 and cause the upper member of t e forked end of said arm 39'to engage the correlated arm of the locking-dog 38 and throw said dog into engagement with the ratchet-wheel 31, whereby the carriage is complete rotation of the carriage the dog is held in engagement with the ratchet-Wheel by the inner edge 42 of the track 29. At the During a end of a complete rotation of the carriage,

during which the heel-surface roller properly 'acts on the vertical edge of the heel, as above described, the arm of the locking-dog again enters the forked end .of'the arm and riding upon the inclined edge of the lower member of said fork causes the acting end of the loc'k-- ing-dog to be disengaged from the ratchetwheel, a suilicient clearance-space 43 at this point being provided for that purpose Upon disengagement of the locking device with the ratchet-wheel the rotation of the carriage It will be observed from this description that the said carriage is caused intermittently to partake of a complete rotation, and this rotation occurs after sufficient heel-stock has been expressed from the mold.

A reciprocating knife 44; is provided, said' knife being connected by a link 45 with the eccentric that operates the plunger-operating arm, as best shown in Fig. 1 of the drawings,

the operation of which is so timed withrelation to the other mechanism. of the machine that after the vertical edge of the heel has been shaped by the roller 26, as'described,

A screw 47, whereby said roller maybe moved to or from the center of the heelseat die 19,

' less removed from the center of said die 19 tothe knife will be projected across the dis and thus caused to travel in paths more or accommodate heels of different Widths and lengths.
